Disclosure of Invention
The invention is based on the object of creating an assembly by means of which an easy-to-carry out assembly of a strip-shaped add-on part at a body part is achieved.
This object is achieved by an assembly according to the invention. The assembly according to the invention has the advantage that the holding element and the add-on part are fixed to one another and to the body part only with a few manipulations. In particular, the working step is eliminated compared to the known solutions, since the holding element and the body part on the one hand and the holding element and the add-on part on the other hand can be fastened to one another at the same time. According to the invention, this is achieved in that at least one of the holding elements can be fastened to the body part by means of a longitudinal movement, and the holding element accordingly has at least one rear element (hindrifflement) which can be brought into a rear position with the add-on part by means of the longitudinal movement for the fixing of the add-on part. The longitudinal displacement of the at least one holding element effects a relative movement both relative to the body part and relative to the add-on part, so that the holding element is fastened to the body part, for example, in a known manner and manner by the longitudinal displacement, and so that the holding element is at the same time fastened to the holding element by the longitudinal displacement followed by the add-on part. By providing the two holding elements with at least one docking element (which interacts with the add-on part for fixing the add-on part), the add-on part can be fastened to the two holding elements by the respective docking element by moving only one of the holding elements in such a way that, for example, by moving one of the holding elements first the docking position between the holding element and the add-on part is reached and subsequently the add-on part is moved further longitudinally together with the holding element, so that the docking element of the other holding element likewise reaches the docking position with the add-on part.
According to a preferred refinement of the invention, it is provided that the trailing element of a first of the holding elements is brought in a first direction by a longitudinal displacement of the first holding element relative to the placement part and the trailing element of a second of the holding elements is brought in a second direction opposite to the first direction by a longitudinal displacement of the second holding element relative to the placement part into a corresponding trailing position with the placement part. This achieves the advantage that the attachment of the add-on part to the holding element is automatically achieved by the holding elements moving out of or pushing into one another. By moving in the opposite direction, the movement can be simultaneously caused by a single tool. When one of the holding elements is immovably fastened to the body part as described above, a relative movement of the holding elements with respect to the add-on part in different or opposite directions is also possible.
Preferably, it is provided that the two holding elements can be fastened to the body part by a longitudinal displacement. This makes it possible to preassemble one of the holding elements unnecessarily. For the fastening by longitudinal displacement, the respective holding element preferably has means which make such a fastening by longitudinal displacement possible, for example as it has been used in the prior art. If the two holding elements are designed for fastening to the body part by longitudinal displacement, they are preferably designed such that they must be displaced longitudinally in opposite directions for fastening. This achieves that the insert part itself does not have to be moved in the case of a longitudinal movement of the two holding elements. This achieves the advantage that the mounting of the add-on part can be achieved by a simple movement.
It is furthermore preferably provided that the respective longitudinally displaceable holding element has an elongated hole for receiving a fastening bolt, in particular a fastening screw, which is fastened to the body part, wherein the elongated hole is configured substantially narrower than the widened head section of the fastening bolt and has an enlarged end section through which the head section of the fastening bolt can be guided. The holding element can thus be simply assembled in that the fastening bolt is guided through the enlarged section and then fixed to the body part by longitudinal displacement (in which the fastening bolt is displaced with its shank, which is narrower than the head section, into the narrower region of the elongated hole). In this case, if the retaining element preferably also has a ramp in the region of the elongated hole, which cooperates with the head region of the fastening bolt, the longitudinal displacement also achieves that the retaining element is pressed by the head section against the body part, as a result of which a particularly firm and loadable connection of the retaining element and the body part results.
Preferably, as already mentioned above, the two holding elements can be fastened to the body part by a longitudinal displacement. This achieves, in particular, the advantage that the two holding elements can be mounted in a simple manner on the body part and, in particular, that the add-on part does not have to be moved in the assembly situation itself, in particular if the holding elements can be fastened to the body part in opposite directions by a longitudinal movement, which results in the advantage that the add-on part is not moved along on the paint or the like of the body part, which could otherwise damage the body part by friction.
It is furthermore preferably provided that the holding elements are configured in the form of a strip and respectively have a displacement means (Schiebemittel) at their ends facing one another, wherein the displacement means are arranged/configured in such a way that they can be acted upon by a force simultaneously by at least one of the holding elements by means of a tool for longitudinal displacement. Thus, advantageously only one tool is required in order to load the two holding elements with the force for the longitudinal displacement. By arranging the displacing means at the ends facing each other, they are brought closer to each other in such a way that, for example, the displacing means can be loaded by commercially available pliers for a manipulation force for longitudinal displacement.
In particular, it is preferably provided that the insert has a recess in the region of the displacement means, through which a tool can be guided in a region-wise manner for the force application of the displacement means. The displacement means is therefore arranged behind the add-on part, so that it is reliably protected against undesired force loading. The recess can be closed after assembly, for example by a cover or a plug, so that contamination is likewise not accessible after the insert. These displacement means can be, for example, receiving recesses which are designed to receive tool tips, in particular the tips of pliers, in order to displace the holding elements longitudinally relative to one another by pressing together the pliers. The latter is configured/oriented in such a way that it reaches the rear position of the add-on part in the case of this corresponding longitudinal displacement.
According to an alternative embodiment of the invention, it is preferably provided that the displacement means are configured to displace the projection. In this case, the displacement means project from the respective holding element and can thus likewise be acted upon with force simply by the tool. In particular, it is provided that the displacement projection projects into a recess of the insert, so that it can be easily reached and manipulated by an operator. It is particularly preferably provided that the displacement projection projects through the recess, so that it can be handled particularly easily.
It is furthermore preferably provided that the end regions of the holding elements facing one another overlap one another, wherein one of the holding elements has a recess in the overlapping region, through which recess the displacement projection of the other holding element protrudes. The holding elements can then not only be displaced relative to one another, but can also be mounted so as to be displaceable relative to one another, so that they overlap in regions. By also providing the end with a displacement means or a displacement projection, it is then advantageous if the displacement projection of the other holding element projects into the recess through the one holding element. It is thereby achieved that the two displacement cams are opposite one another in such a way that, when they are moved closer to one another, the holding elements are pressed apart from one another or are displaced longitudinally. If in this case the displacement cams are then loaded with a pressure/sliding force, for example by means of conventional pliers, this causes the holding elements to be separated from one another or to be moved apart in opposite directions to one another. In contrast to the pulling-up of the holding element, a force introduction is thereby achieved which allows an easier fastening of the holding element and the add-on part.
Preferably, it is provided here that at least one of the holding elements can be pushed/pushed into a receiving recess (Aufnahmetasche) of the insert part by longitudinal displacement at its end facing away from the displacement means. By the respective displacement means or displacement cams being located in the region of adjacent retaining elements and the retaining elements being pressed apart from one another by force application, it is possible to realize that the opposite ends of the respective retaining elements are pushed into the receiving recesses. By the holding element being pushed into the receiving recess in the case of fastening the holding element, a particularly secure locking of the add-on part at the end furthest from the displacement means is achieved, so that likewise when the add-on part (which is in particular the add-on strip) and the holding element are of relatively long construction, a secure fastening/fastening of the add-on part at the body part is also ensured.
It is furthermore preferably provided that the receiving recess of the add-on part and the pushed-in end of the holding element have a latching device for locking the add-on part at the holding element. This achieves an advantageous locking of the respective retaining element in the final assembly position of the add-on part. The latching device preferably has an elastically deformable latching projection which is formed or arranged on the attachment or on the holding element and interacts with a correspondingly complementarily formed latching receptacle in a latching manner on the holding element or in the final assembly position of the attachment.
Detailed Description
Fig. 1 shows, in a simplified exploded illustration, an assembly 1 with an add-on part 2 designed as a strip panel for a motor vehicle, with a body part 3 of the motor vehicle to which the add-on part 2 can be fastened, and with two holding elements 4,5 for fastening the add-on part 2 to the body part 3. The holding elements 4,5 are likewise of strip-like design, wherein their common longitudinal extent approximately corresponds to the longitudinal extent of the add-on part 2, and wherein the holding elements 4,5 are of such a design that they can be completely received by the add-on part 2, so that the holding elements 4,5 are no longer visible in the installed state.
The assembly 1 furthermore has a plurality of fastening screws in the form of fastening screws 6 mounted on the body part 3, which are arranged continuously and at uniform spacing from one another in the longitudinal extension of the add-on part 2. The fastening screw 6 has a head section or screw head 7 and a shank section or screw shank 8, respectively, wherein the screw shank 8 has an external thread which interacts with an internal thread arranged on the body part 3. The fastening screw 6 is screwed into the body part 3 so far that the screw head 7 is spaced apart from the surface of the body part 3.
Fig. 2A and 2B show detailed views of the assembly in the pre-assembly position. In this case, the partial view in fig. 2A shows a top view onto the rear side of the holding element 4 facing the body part 3, which is located below the add-on part 2, and fig. 2B shows a cross-sectional illustration of the assembly 1 along the line a-a according to fig. 2A. The holding element 4 has a plurality of elongated holes 9, wherein the corresponding elongated hole 9 can be associated with one of the fastening screws 7 in the body part 3. Each slot 9 has a narrower, slot-like section and an enlarged end section 10. The elongated hole 9 has approximately the width corresponding to the diameter of the screw shaft 8. The end section 10 has a larger diameter than the screw head 7, so that for assembly, the holding element 4 is first aligned with the end section 10 relative to a respective one of the fastening screws 6 and is pressed onto the body part 3 until the screw head 7 of the respective fastening screw 6 passes through the end section 10. Subsequently, the holding element 4 is moved longitudinally in such a way that the screw shank is pushed into the elongated hole 9, whereby the screw head 7 reaches the rear position relative to the holding element 4. The elongated hole 9 has a latching means 11 next to or adjacent to the end section 10, by means of which the holding element 4 can be locked in its longitudinal extension at the respective fastening screw 6. The latching means 11 is designed such that, in the event of the application of a sufficiently high force for overcoming the particularly elastically deformable latching means 11, a longitudinal displacement of the holding element 4 is possible until, for example, the screw shank 8 abuts against the end of the elongated hole 9 opposite the end section 10.
In the ready-to-install position, in which the screw shank 8 (the screw head 7 is shown in the illustration of fig. 2A only in dashed lines for reasons of clarity) is fixed by the latching means 11, the attachment 2 is then pushed onto the retaining element 4, as indicated by the arrow 12 in fig. 2B. In this case, the push-up is effected onto the body part 3. Fig. 2B also shows that the screw head 7 is then connected to the retaining element 4 from the perspective of the body part 3. The latching means 11 are in this case embodied as projections which project into the elongated hole 9. The placement part 2 grips the holding element 4 in its entirety and is designed in such a way that it can accommodate the holding element 4 together with the fastening screw 6 completely in its interior. The holding element 4 has for this purpose a substantially V-shaped cross section. At its end facing the body part 3, the add-on part 2 has a plurality of rear elements 13 projecting in the direction of the holding element 5. As can be seen from fig. 2A, the rear elements 13 are arranged uniformly and at a distance from one another in the longitudinal extension of the placement part 2. In particular, it is provided that the rear element 13 is formed integrally with the attachment 2. The rear element 13 is spaced apart from the body part 3 and accordingly has a section 14 extending in the longitudinal extension of the add-on part 2, which is oriented obliquely in the longitudinal extension or longitudinal displacement direction. The components 13 of the add-on part 3 are all oriented in the same direction in the region of the holding element 4 in an inclined manner.
The holding element 4 likewise has a rear connection means 15, which are arranged uniformly distributed on both sides of the holding element 4 in the longitudinal direction. When the base body of the holding element 4 is located between the components 13 of the add-on part 2 (as shown in particular in fig. 2B), the components 15 are located in the region of the components 13. The following means 15 likewise has a section 16 which is oriented obliquely as seen in the longitudinal extent of the holding element 4. The attachment means 15 are in particular formed integrally with the holding element 5 or with the base body of the holding element 5. The backing elements 15 and 13 are designed or arranged such that, in the pre-assembly position, the backing means 15 is located between two respective backing means 13 of the placement part 2.
The backing means 13,15 are designed in such a way that when the holding element 4 is moved longitudinally into the final assembly position from the pre-assembly position according to fig. 2A and 2B according to arrow 17, the backing means 15 of the holding element 4 backs the backing means 13 of the attachment 2 and is pulled in the direction of the body part 3 due to the bevel.
The final assembly position is shown by way of example in fig. 3A and 3B, wherein fig. 3A shows a top view onto the assembly again from the perspective of the body part 3, and fig. 3B shows a cross-sectional illustration along the line a-a according to fig. 3A. By means of the longitudinal displacement of the holding element 4, the add-on part 2 is therefore pulled in the direction of the body part 3. At the same time, the holding element 4 is also fastened to the body part 3 by the screw shank 8 moving further in the direction of the end of the elongated hole 9 facing away from the enlarged end region 10 at the body part 3. In particular, it can be provided that on the upper side of the holding element 3 facing away from the body part 3, a chamfer is formed which interacts with the screw head 7 such that, when the holding element 4 is displaced longitudinally in the direction of the arrow 17, the screw head comes into contact with the chamfer and, in the event of further longitudinal displacement, presses the holding element 4 in the direction of the body part 3, as a result of which the holding element 4 is fastened to the body part 3.
The holding element 5 and the placement part 2 in the region of the holding element 5 are basically designed correspondingly to the holding element 4 and the placement part 2 in the region of the holding element 4, with the difference that for fastening the holding element 5 and the placement part 2 in the region of the holding element 5, the holding element 5 has to be longitudinally displaced in a direction opposite to the direction in which the holding element 4 is longitudinally displaced for its fastening (as described above). For this purpose, the slot 9 is correspondingly embodied in the retaining element 5 exactly opposite to one another, so that the enlarged end section 10 is on the other side of the slot 9. Then, when the holding member 4 is moved rightward in the present embodiment, the holding member 5 is moved leftward. The same applies to the trailing means 13 of the attachment 2 in the region of the retaining element 5 and to the correspondingly diametrically oriented trailing element 15 of the retaining element 5, so that in the event of a longitudinal displacement of the retaining element 5 counter to the direction of the arrow 17, the trailing means 15 of the retaining element 5 follows the trailing means 13 of the attachment 2 and in the process pulls the attachment 2 in the direction of the body part 3, so that the attachment 2 is likewise fastened to the body part 3 by means of the retaining element 15.
Fig. 4A and 4B show an advantageous embodiment of the assembly 1, which provides for easy displacement of the holding elements 4 and 5 in opposite directions for the securing of the holding elements and the securing of the add-on part 2.
The inlay 2 has a recess 20 in the region of the ends 18 and 19 of the holding elements 4,5 facing each other. The ends 18 and 19 of the holding elements 4,5 are designed such that they overlap in the assembled state in regions, wherein the holding elements 4 project over the holding elements 5 in sections, as shown in fig. 4A and 4B. The holding element 4 has a recess 21 in the overlap region. The holding elements 4,5 have, respectively, at their ends 18,19, a displacement means 22 or 23, which is respectively configured to displace the projections 24 or 25. The displacement cams 24,25 project from the respective holding element 4,5 in the direction of the recess 20. Here, the displacement cam 25 projects into the recess 21, so that the displacement cam 25 is at the same height as the displacement cam 24. The two displacement cams 25,24 are in the region of the recess 20 of the add-on part 2, so that the operator can now simply guide a pliers or similar tool through the recess 20 to the displacement cams 24,25, so that he applies these displacement cams with force at their respective sides facing away from one another in such a way that the displacement cams 24,25 are moved toward one another, as is indicated by the arrow 4A. This results in the holding elements 4,5 being moved longitudinally in opposite directions, as is shown by the arrows in fig. 4B. In this case, the holding elements 4,5 can be maximally moved longitudinally so far that the moving cams 24,25 abut against one another, as is shown in fig. 4B. Fig. 4A shows the pre-assembly position of the assembly 1 and fig. 4B shows the final assembly position, i.e. when the holding elements 4,5 are moved longitudinally relative to each other and are thus fastened to the body part 3 by means of the attachment means 13,15 and the fastening screw 7.
Fig. 5A and 5B show another embodiment, which can be combined with the above-described embodiments. Fig. 5A and 5B in each case show a top view onto the holding element 4 from the perspective of the body part 3. The inlay 2 has, at its end facing the holding element 4, on its inner side, a receiving recess 26 into which the holding element 4 is pushed in the event of its longitudinal movement. Fig. 5A shows the module 1 again in the pre-assembly position and fig. 5B shows it in the final assembly position. The add-on part 2 has latching recesses 27 at the receiving recesses 26, which interact with latching projections 28 of the holding element 4. In this case, the latching projections 28 and/or the receiving recesses 27 are elastically deformable, so that when the retaining element 4 is moved longitudinally in its final position, the latching projections 28 are pushed into the receiving recesses 26 under elastic deformation and spring back in the latching recesses 27 due to their inherent elasticity, so that they enter in the latching recesses 27 in a form-fitting manner, as shown in fig. 5B. The add-on part 2 is thereby additionally locked in a simple manner at the holding element 4, so that it cannot be automatically unlocked. The latching projections 28 together with the latching recesses 27 form latching means 29 for locking the add-on part 2 and the holding element 4 in their final assembly. The holding element 5 and the attachment 2 are expediently configured correspondingly at the other end of the attachment 2, so that the holding element 5 can likewise be locked at the end face with the attachment 2 by means of a corresponding latching device 29. The assembly 1 is thereby securely fastened and locked to the body part 3 overall.
Fig. 6A to 6F show different embodiment variants of the assembly 1, wherein only the retaining elements 4,5 in the different embodiments are shown for the sake of simplicity. The embodiment according to fig. 6A provides that the holding elements 4,5 accordingly have the previously described oblong holes 9 with enlarged end sections 10 which are arranged at different ends of the oblong holes 9 in order to ensure a longitudinal movement of the holding elements 4,5 in opposite directions. As described previously, the holding elements 4,5 are simultaneously moved in opposite directions for fastening the plating 2.
The exemplary embodiment according to fig. 6B provides that only the retaining element 5 is held so as to be longitudinally displaceable, while the retaining element 4 is already fastened to the body part 3 by simple screwing in the preassembled state and is not longitudinally displaceable in this respect. For assembly, the placement part 2 is then pushed onto the holding element 4, in particular first, so that the following means 13,15 act as described above, and then the holding element 5 is moved longitudinally in order to also fasten the holding element.
Fig. 6C corresponds to the above-described exemplary embodiment, wherein in this case the fixing element 5 is fastened and only the holding element 4 is designed to be longitudinally displaceable.
Fig. 6D shows an embodiment in which the slot 9 does not have an end-side enlarged end section 10. Instead, the holding element 4,5 of fig. 5 is in this exemplary embodiment mounted on the body part 3 in such a way that it is first placed thereon and then the fastening screw 6 is screwed into the body part 3. The fastening of the plating member 2 is then effected as described in the first embodiment.
Fig. 6E and 6F show a corresponding embodiment of embodiments 6B and 6C, in which instead of the enlarged end section 10, the fastening screw 7 is provided at the body part 3 only after the holding elements 4, 5. The fastening of the add-on 2 is effected as described previously.
